The RS2 is a string wound cartridge for OMNI's U25,
OB1, and OB5 Whole House water
filters, the Omni Undersink OT32 as well as the older modelsR12, R14 and Omni Regular Whole House water
filters. It has a smaller micron size than
cartridges RS1 and RS3, which makes it ideal for removing small rust and sediment
particles from your water. This cartridge replaces the RS2
SS and DS.

Because of the product’s limited service life and to
prevent costly repairs or possible water damage, we strongly recommend that the bottom of all plastic housings be replaced
every ten years. If the bottom of your housing has been in use for longer than this period, it should be replaced immediately.
Date the bottom of any new or replacement housing to indicate the next recommended replacement date.
